The primary intent of this work is to investigate computer aided compensator design using classical frequency response techniques in conjunction with the techniques of modern mathematical programming. A computer program to perform the automated design task is presented. This particular algorithm is based on the constrained optimization technique introduced by M. J. Box. In particular, the desired open loop frequency response is specified for a number of discrete frequency points over the frequency range of interest. Then the minimization routine is used to vary the compensator parameters in such a manner as to minimize a cost functional based on the difference between the actual and desired open loop frequency response of the compensated system. To illustrate the algorithm several detailed examples using the program are presented.
